The MAP (Manifold Absolute Pressure - the inverse of vacuum) is usually on the top or side of the throttlebody on a Northstar.
Go into www.rockauto.com and get to your car's emissions and sensors lists. When you find MAP, click on one of the small pictures or INFO ! icons for a larger view. Then find that on your car.
(It's in fuel/air. Any one of the $25-$35 units will be fine, BUT I believe the AIRTEX/Wells picture is incorrect.)
The MAP sensor is part #3
